Dr. Janina Grosch has joined our Collaborative Research Center #ChemPrint as the new #scientific coordinator!

She will be the anchor point between PIs, #doctoral #researchers, the @dfg.de and central units of @fau.de organizing #research, #training, #networking, #reporting, & more.

Welcome Janina!

Prof. Wendy L. Queen and Fatemeh Ghorbannia Delavar after the Master's thesis defense

Congratulations to Fatemeh Delavar who represented @fau.de at EPFL & has just completed her MSc thesis in Sion!

Thanks to the group @lfim-epfl.bsky.social for supporting her!

Fatemeh will now join CTFM & #ChemPrint for her #PhD work at FAU.

Atomic layer deposition meme. In the first panel, the ligands say "This is my surface". In the second panel, they are run over by the next ALD cycle.

Just in time for #pi day -- an anonymous participant of the #ChemPrint winter school came up with a very special #nerd joke: Probably the world's first atomic layer deposition (ALD) #meme!

For the International Women's Day:

Let us remember that on average #women still enjoy less rights & face more hurdles than men.

Let us ensure that in our lab they can blossom!

The contribution of women to CTFM #research proves the benefits of nurturing their talent.

Great day to do some cool #science with the amazing @ctfm-lab.bsky.social #team!

Thinking of those less fortunate than us who are left in the cold... Let us appreciate what we have and behave accordingly!

Dissolve My Nobel Prize! Fast! (A True Story) It's 1940. The Nazis have taken Copenhagen, and physicist Niels Bohr has just hours, maybe minutes, to make two Nobel Prize medals disappear.

If instead of gifting a #Nobel medal to a #dictator you want to save it from him, #chemistry provides the #solution: aqua regia!

Note: potassium triiodide, KI3, obtained by dissolving iodine crystals into an aqueous KI solution, works too.

Breakthrough of the year 2025: the unstoppable growth of #renewable #energy!

#Solar energy is now often the cheapest source of electricity, in addition to being highly decentralized and flexible.

True story:

Paper: Electrolytic current scales linearly w/ length ℓ of cylindrical pore due to geometry

Reviewers 1 & 3: Awesome!

Rev. 2: Wrong, cylinder area scales w/ ℓ^2

Our rebuttal: Ahem, A = ℓ × π r^2

Adv. Mater. editor: Reject unless you add ℓ^2

Us: Nope

Paris said au revoir to cars. Air pollution maps reveal a dramatic change. Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.

“Over the past 20 years, Paris has undergone a major physical transformation, trading automotive arteries for bike lanes, adding green spaces and eliminating 50,000 parking spaces.

Part of the payoff has been invisible — in the air itself.”

Leadership, strategy, real action, common sense. #Paris

Et voila! Case proven.
